It is the hottest sport at the Rio Olympics and its athletes added a touch of glamour to the first two days of competition.

As well as being some of the toughest in the world of athletics, the heptathletes double as models and rank among the most marketable in the business.

While the women of the 100m sprint lit up the stadium and Brit 10,000m champ Mo Farah pulled off a miracle to defend his title, the heptathletes were also the talk of the Rio stadium.

They are super fit and their multi-event training keeps them lean and fierce. For the record they have to complete the 100m hurdles, the high jump, a shot put, a long jump, a javelin throw, 800m and 200m.
